They’re 100%corrosion-free, non magnetic, easy to clean, even dishwasher safe. They need little maintenance and no special care. But remember that a knife is a cutting tool—not a screwdriver and not a prying tool. So like any fine blade, ceramic blades should not be should not be twisted, pressured laterally, or used to cut hard objects like bone. If you keep that in mind, your Boker Ceramic knife will provide many years of exceptional performance and satisfaction.
